SPRAY-NOZZLE.

Patented Dec. 22,1914.

Application filed December 14, 1911. Serial No. 665,632.

which the following is a spec' cation, referenc'e being had therein to the accompanying drawing.

1a This invention relates to spray nozzles and the object of the invention is to provide a nozzle to produce a fan-like spray; which will be simple and durable in construction;

and which can be adjusted to cause the fluid 1%; to come in contact with different portions thereof, thereby providing a nozzle which can be manufactured at a relatively low cost and which will have a long life in the han'ds 'of the user.

In the accompanying drawings, Figure 1 is a plan view of a nozzle embodying my mventionj; and Fig. 2 is a vertical section, takenthrou h thesame. v

In these awings I have illustrated one 25 embodiment of my invention and have shown the same as comprising two ortions, one of'whi'ch has a fiat surface and e other of"whieh has an opening communicating with the source of sup ily and so arranged "so as to cause the fluid disc impinge against the flat surface of the firstmerft'oned portion of the. nozzle. The flat surface of said first-mentioned portion extends to the outer edge thereof and, conse- 85 uently, the fluid which comes-in contact therewith at an acute angle is discharged from the nozzle in the form of a fan-like spra'i In the device here illustrated the nozzle is shown as comprising two disk-like an l'ate's 1 and 2 having their faces flat and ting snugly together. The plate 1 is of a diameter shghtly less than the diameter of the plate- 2 and has an opening 3 extending throu h the same at an acute angle to the face 0- the plhte 2. The plate 1 has secured to the back th'e'reofa socket 45 adapted to be connected with the supply pipe or hose and by' m'eans. of which the opening 3 in the plate 1' communicates with the source of fluid suppl The arrangement of the opening 3 relet' vely to the late 2 is such that the fluid passing from tie outer end thereof will come contact with theadjacent portion of that-plate; As here shown the opening is ca formed in the plate 1 near the edge of the arg'ed therefrom to inner face thereof and the edge of the plate adjacent to the opening is beveled, as indicated at 5, to permit the passage of the fluid. It will be noted that the socket 4 and opening '3 are both arranged at an acute angle to the face of the plate 1, and, consequently, the discharge opening for the nozzle is approximately in alinement with the socket and the supporting pipe or hose.

The action of the fluid, which is usually a chemical solution, will eventually pit the face of the member 2 so as to interfere with the proper formation of the spray. In order that the life of the nozzle may be lengthened and a satisfactory spray formed for a much longer period of time Iprefer to make the member or plate 2 adjustable so that difl'erent portions of the flat surface thereof may be brought into alinement with the discharge opening 3 of the plate 1. In the present instance the plate 1 is provided with a central screw-threaded stud 6 upon which the plate 2 is pivotally mounted and upon which it is confined by means of a thumb nu't 7 By loosening the nut the lates can be relatively adjusted to bring di erent portions of the surfaceof the one member into alinement with the discharge opening of the other member. I have also provided means whereby the nozzle can be freed from accumulations of matter should it become clogged. To accomplish this I have formed a notch 8 in one edge of the disk-like memberQ and by moving this notch into alinement with the openings 3 a straight, un-

obstructed passage is provided for the fluid and the matter which may have accumulated in the openings 3 may be forced out of the same, after which the member 2 may again be adjusted to produce the spray.

While I have here shown and described one embodiment of my invention this has been chosen for the purposes of illustration only and I wish it to be understood that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

- 1. A spray nozzle comprising two members arranged face to face and having their adjacent faces substantially flat, one of said members having an opening adapted to coniinunicate with a source ofIfluid i supply" and arranged to discharge the fluid: against the flat face of theotherrmemberatian acute angle thereto and at apoint removed froni that edge of saidmemberrtoward which ity is directed, said first memberbeing partially cut away beyond said opening to .provldean unobstructed space between "the: discharge 1 municate with a source of fluid supplyand' arranged to discharge the fiuidagainst the: flat face of the other memberat: anacuteangle thereto and at apointremovedfrom the edge thereof, one of saidmembers being: adjustable relatively to the other; of sai members to enable successive portions: of "the flat face of that member fluid impinges to be move outi 'ofithe-path of the fluid, and other portions of'saidiflatl face of said member to be presented to the fluid.
